UNITED STATES PATENT @Fl lQE.

WILLIE G. EATON, OF NASI-IUA, NEW HAMPSHIRE, ASSIGNOR TO NASHUAIVIANUFAC- TUBING COMPANY, A CORPORATION OF NEW HAMPSHIRE.

SHUTTLE.

To all whom it may concern Be it known that I, WILLIE G. EATON, acitizen of the United States, residing at Nashua, in the county ofHillsboro and State of New Hampshire, have invented certain new anduseful Improvements in Shuttles, of which the following is aspecification.

My invention relates to a device for detecting uneven yarn or filling;said device is particularly adapted to be combined with a loom shuttle.

The object of my invention is to provide a detecting device of the typereferred to, particularly adapted to be combined with a loom shuttle inwhich a bobbin, having covered or reinforced yarn or filling thereon,that is filling having a central thread, and yarn spun or wound aroundthe same is used, and my invention consists in certain novel features ofconstruction of my detecting device, as will be hereinafter fullydescribed.

In the use of reinforced or covered yarn or filling on a bobbin in ashuttle, as the yarn or filling is drawn out of the shuttle, as theshuttle passes back and forth through the shed in the operation ofweaving, the covered or reinforced part of the yarn or 'lling is liableto break and become detachedfrom toe central thread, leaving only thecentral thread to be woven into the fabric, and making an imperfectionin the fabric; and further in the spinning or Winding of the covered orreinforced yarn or filling on the bobbin to be used in the shuttle, anun covered portion of the yarn or filling, that is only the centralthread, may be wound on the bobbin, causing, when the bobbin is used inthe shuttle, an imperfection in the fabric.

By means of my improved device, particularly adapted to be combined witha shuttle, the uncovered or non-reinforced part of the yarn or filling,as the yarn or filling is drawn ed the bobbin in the operation of theloom, will be immediately detected, and through this detection, theoperation of the loom will be immediately stopped to prevent the weavingof imperfect goods.

I have shown herein my device for detecting an uncovered section of theyarn or filling, used in connection with a loom shuttle, but it will beunderstood that I do not limit my invention to such use, as saiddetecting device may be used in connection with spin- Speoification ofLetters Patent.

ning frames or winding machines, which handle covered or reinforced yarnor filling.

Referring to the drawing :-Figure 1 is a plan view of the self-threadingend of a shuttle, and of the upper end of a bobbin in the shuttle,having reinforced or covered yarn or filling wound thereon, and mydetecting device combined with the shuttle. Fig. 2 corresponds to Fig.l, but shows a portion of the covered or reinforced yarn or fillingbroken away, leaving only the central thread, which is caught and heldby the detecting device. Fig. 3 shows, on an enlarged scale, a side viewof the detecting device shown in Figs. 1 and 2, detached, and, Fig, 4 isa top or plan view, looking in the direction of arrow at, Fig. 3.

In the accompanying drawing, 1 is the loom shuttle, which may be of anyordinary construction, and has a self-threading derice 2 at thedischarging end thereof.

3 is the upper end of a bobbin, and 4 is the covered or reinforced yarnor filling wound on the bobbin. The reinforced yarn or filling has acentral thread i, which, in the process of spinning or winding the yarnor filling, is covered with additional yarn or filling, forming acovered or reinforced filling of ordinary construction, and used inweaving certain classes of fabrics.

My detecting device 5, shown in this instance combined with the shuttle,consists in this instance of a pin or stud, having in this instance ascrew threaded end 5 to be screwed into an opening in this instancethrough the rear wall of the shuttle, and having the cylindrical shapedend 5, with an inclined slot or groove 5 therein; said slot or groove 5extends in the path of the yarn or filling 4, as it is drawn off of thebobbin, and balloons or circles around the upper end of the bobbin, asthe shuttle passes back and forth through the shed in the operation ofweaving. The slot or cut 5 in the detecting device 5, is of such a widththat it will not receive the full sized covered or renforced yarn orfilling 4, but the same will slide over said slot or cut in theoperation. of weaving, as shown in Fig. l; but the width of the slot orout 5" is such that if the central thread is denuded of its covering ofreinforced yarn, for any reason, the central thread, in the operation ofweaving, will pass into the slot or cut 5 in the detecting device 5 andbe held by the same,

and prevent the further drawing oil of the yarn or filling from thebobbin, and consequently cause the breaking of the yarn or filling onthe pick of the shuttle, and the operation of the filling fork mechanismto stop the loom, and prevent the weaving of an imperfect section in thefabric, all as will be readily understood by those skilled in the art.

It will be understood that the details of construction of my improveddetecting de-' Having thus described my inventiomwhat I claim as new anddesire to secure by Letters Patent is:

The combination with "a shuttle for han-,

dling a reinforced yarn or filling, of a detecting devicein one side ofthe discharging end of the shuttle, and at one side of the tip end ofthe cop or bobbin in the shuttle, said device having a slot or cuttherein which will. notreceive the yarn or filling when it is in itsnormal condition, as it is unwound from the cop or bobbin, but willreceive it in its abnormal condition, as it is unwound from the cop orlOObblIl, and pre vent the further unwinding of said yarn or fillingfrom the cop or bobbin. ,7
